LIB 0.3%: The electorate of Swansea lies between the Central Coast and Newcastle on the peninsulas that separates Lake Macquarie from the ocean. Swansea was one of the surprise gains by the Liberal Party in 2011, but MP Garry Edwards was one of several Liberal MPs who have lost their endorsement as a result of the ICAC inquiry into developer donations.

LIB 1.8%: Squeezed between Liverpool and Campbelltown, the electorate of Macquarie Fields covers the suburbs along the M5 at the northern end of Campbelltown City Council. It was narrowly retained by Labor at the 2011 election but becomes a notional Liberal seat following the redistribution.

NAT 2.0%: Monaro is a classic bellwether electorate and has been won by the governing party at 25 of the 28 elections since 1927. Monaro covers Queanbeyan, Cooma and the snowfields, and draws much of its news and economic growth from neighbouring Canberra. Sitting National MP John Barilaro won the seat in 2015 by defeating Labor's Steve Whan, with Whan returning to re-contest in 2015 after sitting in the Legislative Council for the last four years.

LIB 3.8%: Granville is a western suburbs electorate generally south of the M4 motorway and western rail line near Parramatta. It includes the suburbs of Granville, Merrylands and parts of Guildford, Greystanes and Wentworthville. It had been a Labor seat through most of its history before the victory of Liberal Tony Issa in 2011, had not been won by the Liberal Party since 1935. Issa had more than two decades service on Parramatta Council and several previous unsuccessful tilts at state parliament before his victory in 2011. He will be opposed at the 2015 election by Labor's Julia Finn, a Parramatta City Councillor since 1999 and a former Lord Mayor.

MP Darren Webber will not be re-contesting. The new Liberal candidate will be Susan Kerr, while the former Labor MP for the seat David Harris will re-contest in 2015.

LIB 4.9%: This electorate of Maitland is based on the mining and industrial city of Maitland and its surrounding suburbs and townships.

It includes the suburbs of St Marys, Cambridge Downs, Werrington County, Cambridge Park, Werrington, Werrington Downs, Claremont Meadows, Oxley Park, Colyton, Willmot, Lethbridge Park, Tregear and Whalan. The electorate has been significantly changed by the redistribution, the Liberal margin down from 12.3% to 5.3% as Richmond and areas north of the Hawkesbury River have been removed. Sitting MP Bart Barrett is not re-contesting after trying to switch seat and then become one of the victims of the ICAC donations inquiry. The new Liberal candidate is Bernard Bratusa, opposed by Labor's Prue Car.

LIB 5.4%: Blue Mountains is a bellwether electorate, having gone with government at every election since 1976. The physical area of the electorate consists mainly of National Park, with the population of the district clustered along the rail/highway corridor between Blaxland and Mount Victoria.

LIB 6.8%: The electorate of Campbelltown includes the Campbelltown Town Centre as well as the suburbs to the south. Campbelltown was a Labor seat from 1971 until the victory of Liberal Bryan Doyle in 2011, one of the beyond expectation victories for the Liberal Party. Doyle's position has been strengthened by the redistribution but he will still face a major challenge to retain this seat. His Labor opponent is Greg Warren, chosen by the first of Labor's new community pre-selection ballots.

NAT 6.8% v IND: A New England based seat that includes the regional centres of Tamworth and Gunnedah as well as Manilla, Barraba, Werris Creek, Walcha and Nundle. This would normally be a safe national seat, but it has a strong Independent streak in recent decades, held by Tony Windsor 1991-2001 and Peter Draper 2003-2007. Draper was defeated by current National MP Kevin Anderson in 2011, but Draper returns to the contest in 2015. Opposition to coal seam gas and coal mining on the Liverpool Plans are big issues in the electorate.

LIB 8.3%: Coogee is the eastern suburban electorate that stretches from Bondi Road in the north to South Coogee, east of Centennial Park and Randwick racecourse. The electorate includes the suburbs of Waverley, Bronte, Clovelly, Coogee, Randwick and parts of Bondi and Bondi Junction. It is the state's second smallest electorate at just 12.7 square kilometres. While Coogee had long been a marginal seat that increasing property values suggested was trending towards the Liberal Party, it had been held by Labor continuously from 1974 until gained by Liberal Bruce Notley-Smith in 2011. His Labor opponent will be Labor's defeated MP from 2011, Paul Pearce, while the Greens have nominated Lindsay Shurey.

LIB 8.6%: Kiama is a mixed electorate that extends from the southern Illawarra to the Shoalhaven River then west into the Morton National Park. In its centre lies the Kiama council area, the electorate extending south to take in parts of Shoalhaven Council north of the river.

Kiama was won by the Liberal Party's Gareth Ward at the 2011 election, the first Liberal victory since the electorate re-appeared on the state's electoral map in 1981. The Labor candidate in 2015 is Glenn Kolomeitz.

LIB 8.8%: Seven Hills is a new electorate between Parramatta and Blacktown that replaces the abolished seat of Toongabbie. It lies to the east of the abolished electorate and is several percentage points safer for the Liberal Party. Sitting member for Toongabbie and former Premier Nathan Rees will be retiring. The new Labor candidate is Susai Benjamin, opposed by Hills Shire councillor Mark Taylor for the Liberal Party.

LIB 10.7%: Holsworthy is a radically re-drawn electorate that represents a westward shift of the abolished electorate of Menai. It some residual western suburbs of Sutherland Shire, but now largely consists of Liverpool City Council suburbs including Chipping Norton, Moorebank, Wattle Grove, Hammondville, Lurnea, Prestons and parts of Casula. The electorate includes and is named after the Holsworthy Army Barracks. The redistribution halves the Liberal margin compared to the old seat of Menai. Liberal MP for Menai, Melanie Gibbons, will re-contest after first winning Menai in 2011. Her Labor opponent is Charishma Kaliyanda.

LIB 11.5%: The Entrance is a Central Coast seat with two distinct ends, one in the northern suburbs of Gosford, and the other around The Entrance and southern shore of Tuggerah Lake. It is another Central Coast seat where Liberal prospects have been damaged by the ICAC inquiry into developer donations, with MP Chris Spence forced to stand aside from the party. He is not contesting the 2015 election. The new Liberal candidate is Michael Sharpe, opposed by Labor's David Mehan.

LIB 12.4%: Mulgoa covers Sydney's outer-west to the south of the M4 motorway, running from Cowpasture Road in the east to the Nepean River in the west. It includes Cecil Hills, Abbotsbury, St Clair, Erskine Park and Glenmore Park. It was gained at the 2011 election by Liberal Tanya Davies, and she will defend the seat in 2015 against Labor's Todd Carney.

LIB 14.7%: Centred on Port Stephens to the north of Newcastle, this district takes in Tea Gardens and Hawks Nest on the northern shore of Port Stephens, and Nelsons Bay, Soldiers Point, Lemon Tree Passage and Mallabula on the south side. The electorate also includes Karuah, Medowie and Raymond Terrace. Port Stephens was one of the Liberal gains in 2007 when it was won by current MP Craig Baumann. He was one of the Liberal MPs revealed in the ICAC to have accepted developer donations while in local government. Baumann will not be re-contesting and the new Liberal candidate is Ken Jordan. His Labor opponent is Kate Washington, the defeated Labor candidate in 2011.

LIB 16.1%: Lying on both sides of the Nepean River, the electorate of Penrith includes the Penrith CBD, South Penrith, Kingswood, Jamisontown, Cambridge Gardens and Cranebrook on the east bank of the river, and Emu Plains, Emu Heights, Leonay, Lapstone and Glenbrook to the west. Penrith was gained by the Liberal Party's Stuart Ayres at a 2010 by-election, the 25% swing revealing the extent of the drubbing that Labor faced at the 2011 state election. Ayres is now Police and Emergency Services Minister and will be opposed at the 2015 election by Labor's Emma Husar. The contest will be complicated for former Liberal MP for Lindsay Jackie Kelly contesting the seat as an Independent opposed to the construction of a new airport at Badgerys Creek.

NAT 21.7%: At the top end of the North Coast, Tweed is the state's most northerly electorate and covers the coastal strip of Tweed Shire along the new route of the Pacific Highway from near Mooball to the Queensland Border. The seat is dominated by Tweed Heads but also includes Tumbulgum, Bogangar, Pottsville and Burringbar. It has been held by National MP Geoff Provest since 2007, and while not marginal based on 2011 election figures, would be a Labor held seat based on 2013 federal results. The Labor candidate is Ron Goodman.

LIB 23.0%: On its new boundaries Miranda runs along the southern shore of the Georges River from Taren Point to Alfords Point generally north of President Avenue. This boosts the Liberal margin based on 2011 results, but the contest in Miranda has been complicated by the resignation in 2013 of Liberal MP Graham Annesley, and the victory of former Labor MP Barry Collier at the subsequent by-election in October 2013. Collier will resume his retirement at the 2015 election, so Miranda is shown with a Liberal margin based on the 2011 result and the redistribution. The new Labor candidate is Greg Holland and he will be opposed by the Liberal Party's Eleni Petinos.

NAT 24.6%: Ballina is a far north coast electorate that takes in the Ballina and Byron Shire Councils. Major centres include Ballina, Alstonville, Lennox Head, Byron Bay, Brunswick Heads, Ocean Shores and Mullumbimby. Ballina was first contested at the 1988 election and in the 27 years since has known only one MP, the retiring National member Don Page. Without his personal vote this seat becomes vulnerable for the Nationals, with Labor having a majority in the seat based on recent Federal results. One factor in the Nationals favour is optional preferential voting, which will weaken the flow of preferences between Labor and the Greens. The new National candidate is Kris Beavis, and he will be opposed by Labor's Paul Spooner and the Green's Tamara Smith. Former Green turned Independent Ballina Shire Councillor Jeff Johnson is also contesting.

LIB 26.8%: Goulburn covers all the communities along the Hume Highway from Berrima to Yass with the largest centre being Goulburn, but also including Moss Vale, Robertson, Boorowa and Crookwell. Goulburn has been held by Planning Minister and former journalist Pru Goward since 2007, but boundary changes have moved her electorate to the west, gaining substantial territory from the abolished National Party seat of Burrinjuck. The Nationals had intended to contest Goulburn, but were talked out of it for reasons of Coalition harmony. Labor has chosen a high profile local candidate in former Labor Party State President and Senator Ursula Stephen, and Labor has been stoking the fires of Coalition disharmony by suggesting Labor's candidate is the best to represent National Party voters.

Labor

ALP 9.3%: The electorate of Wollongong is centred on the Wollongong CBD and the Port Kembla steelworks and associated port and industries, and also includes the surrounding suburbs on the northern shore of Lake Illawarra. The seat has been traditional Labor heartland, but Labor's grip has been challenged in the past by Independents. Former Wollongong Lord Mayor Frank Arkell represented the seat as an Independent from 1984 to 1991, and current Lord Mayor Gordon Bradbery gave Labor's grip a shake in 2011. The Greens also won the local Federal seat of Cunningham at a 2002 by-election. Controversial Labor MP Noreen Hay has represented Wollongong since 2003, but she faces a challenge in 2015 from Arthur Rorris, who has resigned from the Labor Party and his job as Secretary of the South Coast Labour Council. The Liberal candidate is racing driver Cameron Walters and the Liberal Party has suggested they will direct preferences in an attempt to defeat Hay.

Independents/Greens

IND 0.3% v LIB: The electorate of Sydney covers the Sydney CBD and surrounding suburbs, including Pyrmont, Darlinghurst, Woolloomooloo, Kings Cross, Elizabeth Bay, Potts Point, Paddington and parts of Surry Hills, Edgecliff and Woollahra. Sydney was formerly held by Lord Mayor Clover Moore, but she was forced to choose between Town Hall and Parliament in 2012, resigning her seat but seeing her anointed successor Alex Greenwich win the seat at a by-election. His opponents in 2015 will be Liberal Patrice Pandeleos and Labor's Edwina Lloyd.

GRN 0.4% v ALP: The electorate of Balmain is based on the Balmain Peninsula to the west of the Sydney CBD. It takes in all of the Leichhardt Council areas, including Birchgrove, Balmain, Rozelle, Lilyfield, Leichhardt and Annandale, as well as Glebe from Sydney City Council. Once a working class heartland where the NSW Labor Party and many of the state's unions had their birthplace, Balmain is now heavily gentrified, one of the state's most affluent electorates, and a hotbed of Green and alternative politics. It was won by the Green's Jamie Parker in 2011, defeating then Labor MP and Minister Verity Firth, who returns to try and recover this seat in 2015. The Liberal candidate is Lyndon Gannon.

GRN 4.4% v ALP: Newtown is the state's newest, smallest and funkiest electorate, covering just 10.3 square kilometres. It runs in a narrow strip from South Dowling Street to Taverners Hill south of Parramatta Road and Foveaux Street. It includes Surry Hills, Redfern, Chippendale, Darlington, Newtown, Enmore, Stanmore, Petersham and parts of Marrickville and Lewisham. An area that once upon a time would have been Labor heartland, these days Labor faces a strong challenge from the Greens in this part of Sydney. Labor's candidate is MLC Penny Sharpe, opposed by Green candidate Jenny Leong and the Liberal Party's Rachael Wheldall.
